Functions Of water In Our Bodies.

Water is required for all chemical reactions in our cells. These are functions of water in our bodies:
* Water regulates body temperature.
* Water promotes healthy skin.
* Water is a natural lubricant for joints.
* Water moves nutrients around the body.
* Water removes waste from the body.
* Water helps with digestion.

Water is our body's principal chemical component and takes up the larger percentage of our body weight. Every system in our body depends on water. For example, water flushes toxins out of vital organs and carries nutrients to our cells. Water in our body generates blood, distributes nutritive elements and eliminates waste matter. It controls temperature and helps digestion. Most importantly, water revitalizes body cells.

When we were embryo, we were mostly water. The quantity of water in our bodies decline as we age.
A seven-week old embryo is composed of 95% water.
A seven-week old baby has 75-80% water.
An adult has 65-70% water and the aged 50%.
It is clear from these percentages that water content is a guide on the state of health of the body.

Water is the only substance in the planet that has three physical states solid, liquid and gas. The states makes water a powerful solvent that carries many invisible ingredients as minerals, oxygen, nutrients, products of waste and pollutants. Obviously, life can not exist without water.

How We Create Problems for Our Teeth.

We can prevent problems by eating fewer sugary snacks and sugary drinks. Sugar can hurt our teeth and cause tooth decay, or cavities. They encourage hostile organisms like bacteria to thrive. Regular consumption of foods with a high acid content, such as citrus fruits, tomatoes, pickles, and tea, can cause enamel erosion.

The symptom of problems with our teeth can be a sharp and sudden pain shoot deep into the nerve endings of our teeth. The pain is triggered with hot, cold, sweet, or sour foods and drinks, or even by breathing cold air through the mouth. There are many other factors that can cause problem for our teeth, these factors include:

-Brushing too hard.
-Using a hard-bristled toothbrush.
-Grinding or clenching our teeth.
-Our age (Tooth sensitivity is highest between the ages of 25 and 30).

These are what we can do to reduce the problems with our teeth:

-Maintaining good oral hygiene.
-Following proper brushing and flossing techniques.
-Use of a soft bristled toothbrush (this will result in less toothbrush abrasion to the tooth surface and less irritation to the gums.
-Brushing gently and carefully around the gum line.

Brushing our teeth with fluoride toothpaste is good when it comes to keeping our teeth in tip-top shape. We should try to brush after eating or at least twice a day. It's especially important to brush before bedtime.

To avoid the problems I caused for myself over the years, here is the best way to brush our teeth: go around and around until you have covered every surface of every tooth. Brush up and down, rather than side to side. You can also brush your tongue to help keep your breath fresh. I have ignorantly caused problems for my teeth over the years due to abnormal brushing with using a hard-bristled toothbrush. It resulted in abrasion to my tooth's surface and gums thereby exposed the dentin.

The part of the tooth we can see, which is not covered by the gum is covered with enamel which is very hard and often shiny. Enamel is a very tough substance and it acts as a tooth's personal bodyguard. Enamel works as a barrier, protecting the inside parts of the tooth. If we were able to peel away the enamel, we would find dentin. Dentin makes up the largest part of the tooth. Although it is not as tough as enamel, it is also very hard. Dentin protects the innermost part of the tooth, called the pulp. The pulp is where each tooth's nerve endings and blood supply are found.

When we take hot, cold, sweet, or sour foods and drinks, or even breathing cold air through the mouth, it's our pulp that hurts. The nerve endings inside the pulp send messages to the brain about what's going on. The pulp also contains the tooth's blood vessels, which feed the tooth and keep it alive and healthy. The pulp goes all the way down into the root of the tooth, which is under the gum. Cementum makes up the root of the tooth, which is anchored to the jawbone.

Our teeth are great for chewing, but we also need them to talk. Different teeth work with our tongue and lips to help us form sounds. Try saying the word "tooth" slowly and notice how your tongue first hits the inside of your incisors to produce the "t" sound and then goes in between your upper and lower teeth to make the "th" sound.

You can prevent and resolve problems with your teeth if you follow the tips. It's also important to visit experts — dentists.

If you take care of your teeth now, it will take care of you for the rest of your life.

Our Immune System

The Immune System.

To be immune means to be protected. So it makes sense that the body system that helps fight off sickness is called the immune system. The immune system is made up of a network of cells, tissues, and organs that work together to protect the body. White blood cells, also called leukocytes, are part of this defense system. There are two basic types of these germ-fighting cells. One is phagocytes, which chew up invading germs. The other one is lymphocytes, which allow the body to remember and recognize previous invaders. Leukocytes are found in lots of places, including our spleen - a small organ near the stomach that controls the quality of blood cells and helps fight infections.

Leukocytes also can be found in bone marrow, which is a thick, spongy jelly inside our bones. Our lymphatic system is home to these germ-fighting cells also. Our lymphatic system is in form of swollen "glands" on the sides of our necks. Although we call them "glands," they are actually lymph nodes and they contain clusters of immune system cells. Normally, lymph nodes are small and round and you don't notice them. But when they're swollen, it means your immune system is at work. Lymph nodes work like filters to remove germs that could hurt you. Lymph nodes, and the tiny channels that connect them to each other, contain lymph, a clear fluid with leukocytes (white blood cells) in it. We have lymph nodes in several other places on our body: behind our knees, in our armpits, and in our groin - just to name a few.

Though we have this great system in place, it's not enough to keep us from getting sick. Well, everyone gets sick sometimes. But our immune system helps us get well again. Sometimes a person has a problem with his or her immune system. Allergies are one kind of problem. It's medical condition that causes one to react badly to a particular substance. The immune system overreacts and treats something harmless as something really dangerous to the body .

Other immune system problems may develop due to an illness like cancer or HIV/AIDS - an immunodeficiency condition. It's a medical condition in which the body does not have the normal ability to resist infection.

We can't prevent most immune system disorders, but if they happen, they can be treated with medicine and we will feel good and be healthy again. Immunologists are doctors who specialize in immune system problems. So if anyone has an immune system problem, the doctors can help and such a person will stay strong and be able to fight off illness.

We can help our immune systems with hygienic practices, eating nutritious foods, getting plenty of exercise, and getting regular medical checkups. - You may like to read: Note on Our Health.
